A new catchment gully erosion model for a healthier Great Barrier Reef

沉积物影响大堡礁的水质和珊瑚健康。河流集水区沟渠的侵蚀是沉积物的主要来源。该项目旨在开发一种新的集水区水平建模工具，使土地管理者能够比较修复方案并确定最佳行动。该项目将产生应用数学方面的新知识，利用创新的模型仿真技术对流域规模的过程进行深入了解。预期的结果包括一个有效的土地恢复决策工具，通过提高实现2050年珊瑚礁政策目标的能力，使自然资源管理者和土地所有者都受益，通过发展自然资本市场。

Sediment impacts Great Barrier Reef water quality and coral health. Erosion of gullies within a river catchment are the dominant source of sediment. This project aims to develop a novel catchment level modelling tool, allowing land managers to compare rehabilitation options and identify optimal actions. The project will generate new knowledge in applied mathematics, using innovative model emulation techniques to bring process insights to the catchment scale. Expected outcomes include a validated land rehabilitation decision making tool, benefiting both natural resource managers by increasing ability to meet Reef 2050 policy targets and landowners though development of Natural Capital Markets.
